Cisco Cisco IOS Software Release 12.2(35)SE

(Optional) Ensure that you have IP connectivity to the TFTP server by entering this privileged EXEC 
command:

Switch# ping tftp-server-address

By default, ping is supported on network node interfaces (NNIs), but you cannot ping from a 
user network interface (UNI) because the control-plane security feature drops ICMP response 
packets received on UNIs. See the “Troubleshooting” chapter of the software configuration 
guide for methods for pinging from the switch to a host connected to a UNI. 

For more information about assigning an IP address and default gateway to the switch, refer to the 
software configuration guide for this release. 

Download the image file from the TFTP server to the switch. If you are installing the same version of 
software that is currently on the switch, overwrite the current image by entering this privileged EXEC 
command:

Switch# archive download-sw /overwrite /reload 

[[//location]/directory]/image-name.tar

The /overwrite option overwrites the software image in flash memory with the downloaded one. 

The /reload option reloads the system after downloading the image unless the configuration has been 
changed and not saved.

For //location, specify the IP address of the TFTP server.

For /directory/image-name.tar, specify the directory (optional) and the image to download. Directory 
and image names are case sensitive.

This example shows how to download an image from a TFTP server at 198.30.20.19 and to overwrite 
the image on the switch:

Switch# archive download-sw /overwrite 

You can also download the image file from the TFTP server to the switch and keep the current image by 
replacing the /overwrite option with the /leave-old-sw option.

For recovery procedures, see the “Troubleshooting” chapter in the software configuration guide for 
this release.

You can assign IP information to your switch by using these methods:

The CLI-based setup program, as described in the switch hardware installation guide.

The DHCP-based autoconfiguration, as described in the switch software configuration guide.

Manually assigning an IP address, as described in the switch software configuration guide.
